ונפן ונסע המדברה. אִלּוּ לֹא חָטְאוּ הָיוּ עוֹבְרִים דֶּרֶךְ הַר שֵׂעִיר לִכָּנֵס לָאָרֶץ מִן דְּרוֹמוֹ לִצְפוֹנוֹ, וּבִשְׁבִיל שֶׁקִּלְקְלוּ הָפְכוּ לְצַד הַמִּדְבָּר, שֶׁהוּא בֵין יַם סוּף לִדְרוֹמוֹ שֶׁל הַר שֵׂעִיר, וְהָלְכוּ אֵצֶל דְּרוֹמוֹ מִן הַמַּעֲרָב לַמִּזְרָח דרך ים סוף. דֶּרֶךְ יְצִיאָתָן מִמִּצְרַיִם שֶׁהוּא בְּמִקְצוֹעַ דְּרוֹמִית מַעֲרָבִית; מִשָּׁם הָיוּ הוֹלְכִים לְצַד הַמִּזְרָח: ונפן ונסע המדברה THEN WE TURNED AND JOURNEYED INTO THE WILDERNESS — If they had not sinned, they would have passed by the way of Mount Seir to enter the Land from its south to its north, but because they became degenerate they had to turn towards the wilderness which is between the Red Sea and the south of Mount Seir, and they proceeded along its southern side from the west to the east, דרך ים סוף BY THE ROUTE FROM THE RED SEA — i.e. by the route which they had taken on leaving Egypt which is at the south-west corner. From there (where they were at that moment) they went towards the east.
ונסב את הר שעיר. כָּל דְּרוֹמוֹ עַד אֶרֶץ מוֹאָב: ונסב את הר שעיר AND WE COMPASSED MOUNT SEIR, the whole of the south side as far as the land of Moab.
